Google may be in hot water with the Canadian Competition Bureau. Documents filed to the Federal Court of Canada describe Google as controlling at least one market related to search and advertising, potentially raising anti-trust concerns. The documents also suggest Google may have engaged in a number of anti-competitive acts by manipulating search results to favor their own products, or preventing data export from the companys AdWords platform. This isnt the first time Google has faced regulatory scrutiny over its ad and search practices.
